The number of mitochondria in a cell is an indicator of the extent of active transport. Mitochondria are responsible for generating ATP, the energy currency of the cell, through a process called oxidative phosphorylation which requires the active transport of ions such as H+ across the inner mitochondrial membrane. Therefore, the more mitochondria a cell has, the greater its capacity for active transport. Diffusion, facilitated transport, and osmosis do not rely on mitochondria for their mechanisms.
